Default Interesting problem

Last night I was experimenting with various ways to enter trial-factoring assignments that are larger than Primenet's range. I tried the following formats:

Factor=240000011,-1
Factor=240000011,0
Factor=240000011,27

None of these worked. Each time Prime95 returned "Bad Factoring Assignment." Was I doing something wrong?

To put it bluntly, yes. Prime95 is not designed to factor any exponent above 79300000, and so it takes 240000011 as a bad assignment. However, there is an advanced factor feature that does allow factoring over 79300000. For the range you have reserved, try putting this line into worktodo.ini:

AdvancedFactor=240000000,250000000,0,50

If you do at first (it's very fast)

AdvancedFactor=240000000,250000000,0,32

and after that

AdvancedFactor=240000000,250000000,33,50

you can get get much more factors (unfortunately not yet all up to 50 bit).
